GPS Devices Damaging Thousands Of Bridges?

from the ignore-your-navigation-system dept

In the past, we've seen stories of GPS navigation devices not knowing enough about local roads that the directions were often inappropriate for the type of vehicle -- especially trucks. It had resulted in signs being placed on roads, begging drivers to ignore their own navigation devices. Engadget now points us to a report from the UK suggesting that bad directions from navigation devices was responsible for damage to about 2,000 bridges. That seems like quite a lot. The claim is that the devices direct trucks who are much too heavy to go over bridges not designed for that kind of load. Work is now being done to get the navigation companies to at least understand the types of roads and bridges, and how that corresponds to different types of vehicles.

    Maybe what they need to do

    Is provide better information.

    Input the weight of the vehicle (Laden and Unladen?) into the GPS.
    Have load bearing information of the bridges in the map.

    If the weight of the vehicle exceeds the bridge, it's a null route.
    Maybe even provide routes for Laden and unladen weights in a different colour.

    Not sure what information can be out into a GPS map, so no idea if this would work.
